Title: A cable clamp for use with an electrical connector
Inventor: PAULLUS CLARENCE LEONARD
IPC: H01R13/436
Filed: 1966-05-19
Abstract: 1,131,518. Two-part couplings. AMP. Inc. 19 May, 1966 [9 June, 1965], No. 22322/66. Heading H2E. A cable clamp is prevented from proper attachment to an electrical connector having an externally movable contact-retaining member until the member is in the contact-retaining position. One part of a two-part connector with clamp improperly attached is shown in Fig. 2, the other connector part being similar in construction. An eccentric camming ring 46 is rotatably mounted on connector shell 6 to laterally displace a relatively rigid insert 30 whereby neighbouring, relatively soft inserts 28, 32 (e.g. neoprene rubber) are deformed so as to retain the contacts 38. The ring 46 is locked in this position when an ear 52 on a split spring washer 54 enters a deep notch 50 in the ring. The cable clamp, which may be of elbow or straight form, is in two parts 64, 66 which may then be properly attached to the connector by means of interengaging lugs 78 and recesses 80 and screwed together. The ear 52 may initially enter a shallow notch 52 in the ring 46, or may abut the edge of the ring 46 whose flange may be sufficiently wide to prevent all but proper attachment. The shell 6 contains inserts 34, 32, 30, 28, 26 and (24) (Fig. 1, not shown) to locate the contacts 38, while a sealing insert (22) may be located between the faces of the mating connector parts which may themselves be locked together by means of a locking ring (10) on shell 6 engaging a peg (14) on the mating connector shell (4).

Title: Improvements in radio communication
IPC: H04B3/54
Filed: 1927-09-08
Abstract: 277,353. Dubilier Condenser Co. (1925), Ltd., (Assignees of Nyman, A.). Sept. 8, 1926, [Convention date]. Relaying systems; wired wireless systems : secret, signalling systems; thermionic generators. - Messages are sent along conductors by means of oscillations of relatively low frequency, and are converted to a frequency suitable for radiation at a plurality of points on the conductor, and are radiated from aerials at those points. Signals are transmitted along a power line 3 on a frequency such as twenty or thirty kilocycles and are picked up by the relaying apparatus enclosed in a casing 6 which is connected across a coil 9 in the line. The relaying apparatus consists of a modulator M and an oscillator O so that the signals are radiated from a suspended aerial 21 as modulations on an intermediate frequency imposed on a higher frequency, for example one or two thousand kilocycles. A suitable receiver therefore contains two detectors, one tuned to the higher frequency and the second tuned to the lower frequency. The relaying apparatus is operated by moving a switch arm 34, Fig. 3, upwards so that a link L lifts a plunger 44 to bridge contacts 42. Current then flows from a transformer 31 through a lead 39 to the filament of valves M, O and returns by contacts 42, solenoid 45, constant-current resistance 37 and lead 33. The upward movement of link L makes the lower end slip past an arm A and the plunger is then held up entirely by the coil 45. If either of the filaments burn out and the coil 45 consequently becomes de-energized, the plunger drops to bridge contacts 42' and thus lights the reserve valves M<1>, O<1>. An automatically actuated relaying-apparatus is shown in Fig. 4. When a ten-cycle signal, for example, is transmitted along the line and passes through a coil 48 which is tuned to that frequency by a condenser C, a switch member 44 closes the filament circuit of valves 13, 15. On the other hand a twelve cycle signal, for example, affects a coil 48<1>, which is tuned by a condenser C<1> and wound oppositely to the coil 48, and moves the plunger 44 away from contact 42. Alternatively the disconnecting signal is dispensed with, and the plunger is pulled by a spring against the action of the coil 48. In this case the tencycle signal is transmitted throughout the signalling.
